Ok... So I did my "use it up" batch. Somewhere between 11 and 12 lbs of Muntons Super Light LME, a pound of Weyermanns hefe-wheat lme. A couple pounds of mixed dark and crystal grains. The OG was somewhere between 1.080 and 1.090 or so. I used a saved batch of Wyeast 1056. It pretty much quit at around 1.032. What say y'all geniuses? Is it done? Add a pack of Safale? It still tastes pretty sweet to me but not so bad with the 2 oz of galena that went in.. It doesn't seem like it is doing much in the secondary. What's the group think? Ed

If you had exactly a 5 gallon batch and 12 lbs of Muntons, the LME alone will give you around a 1.093 OG, plus a bit for the grains. I'd probably guestimate it at 1.095. If 11 lbs of Muntons, then the LME would give you around a 1.086 OG, call it 1.088 with the grains. Of course, all this will change if you had more than 5 gallons in the fermenter. 1.095 to 1.032 is 66% attenuation. 1.088 to 1.032 is 64% attenuation. I would have expected a little more attenuation from Muntons, but it's gotten pretty far. I think the chances of the yeast being stuck are fairly low. A stuck fermentation usually happens much earlier, if there really are yeast health issues going on. IOW, it's hard to imagine the yeast being active enough to drop it from 1.095 all the way down to 1.032 and then deciding that they're too sick to continue. How long has it been sitting at 1.032? Maybe it's still dropping slowly? > What say y'all geniuses? Is it done? I'm not a genius, but I'd vote to give it a little bit more time (unless it's already been sitting at 1.032 for a while). If that doesn't change anything, I'd say you're pretty much done. Are you disappointed in the attenuation, or do you just want to confirm that it sounds like it's finished? John.

I always put at least 5.5 gal. in the fermenter. For a stout (when I expect extra trub, I don't get too excited about straining into the primary) I put a quart more... since this was using up left overs, I didn't measure exactly the amount of extract. I entered 11 lbs in recipator but it was probably more like 12 or maybe a bit more... which is significant come to think of it. So ok, the 1.085 is probably on the low side. The 1.032 is measured and that was after a week when I racked to the secondary. I haven't seen any activity other than the gradual clearing I always notice in the secondary. I'm going to let it sit anyway... typically I get another few points after racking so maybe it'll go down a little. From all the input so far, it is as I thought... just done. No disappointment. A little education perhaps (grin) and confirmation. The point of the batch was to not throw away the extract and end up with something I could drink. I think I've accomplished both. Unless it changes significantly from when I racked, it is going to be a nice little winter warmer (or dessert beer perhaps.) At basement temp (around 60-65F) it ought to be just about right. Ed

I have found Muntons LME to be about 65% fermentable. Going from 1.085 to 1.032 is 62% so that is probably all you will get.

The unfermentables in extract are cumulative - they add up - and produce high finishing gravities. The way around this is to choose higher attenuating extracts like United Canadian at 85% or use sugar instead of some of the extract.

I'd definitely agree with Dan. If you want a dry, all extract, big beer then using sugar is a good idea. John.

You said it was leftovers, one thing I've wondered is if age will have an affect on the fermentability of the LME? Mark R

I don't know for certain, but I would guess no. In order to do that you'd have to be breaking sugars down in the extract with age. I think the only way that is going to happen is if there are active enzymes. That would make it more fermentable though, not less. In order for the attenuation to decrease over time you'd have to somehow be turning simple sugars in the extract back into complex ones somehow. I would guess that neither are going to occur. Age will definitely have effects on the flavor, but I doubt it would have an effect on the fermentability. John.
